2004 BMW 325i

About a month and a half ago my every day driver was stolen from my apartments and I purchased this vehicle to get me to and from work. I lost all hope but last week the police found and returned my car. I now am looking to sell this or trade for some sort of decent motorcycle. Pros: it runs and drives. Heater & ac work (as far as I can tell). Has sub hook ups and decent stereo. I purchased it from Washington and drove it back to beaverton area no issue. I had contiuned to drive it to work every day until my car was returned. Cons: I asked the kid I bought it from on offer up directly if there were any leaks and he told me no, but I don't know how truthful that was. He did say there is a sensor and when the car is in high rpm it shuts off and you are able to just turn the key back and forth and the car engages perfectly fine again. He said he drove it like that for a long time and as long as you ease onto the gas you don't have that issue. I am not a mechanic what's so ever but from the little research I've done it seems like a crankshaft sensor and they seem like an easy fix. Please let me know if you have any offers. Thanks so mucb.
